Schedule10 min notes, then work on graph

Explain each step each day

Day 1 start, get chart done

can work with neighbor! Can’t change seats

Day 2 CHECK CALCULATIONS!,

show example graph, get graph done & plotted

stress what students are to plot (just depth ft & distance km)

Day 3 color, do questions, finish for hw

(maybe a little time on a fourth day)

Bell Work 10/13• 1 fathom = 1.8 m 1 km = 1000 m 1 fathom = 6 ft

1.500 fathoms = ? feet

2.777 fathoms = ? feet

3.500 fathoms = ? meters = ? kilometers

4.777 fathoms = ? meters = ? kilometers

5.How many times bigger is 2500 than 500?

Today you are going to…

Learn the 3 strange ocean units and be able to convert between them.

So you can

Complete the Ocean Profile Graph & answer the accompanying questions.

You’ll know you’ve got it when you

can answer the questions on the graph

Graph Info• Graph Horizontally• Start 4 down, 5 in (zero point)• On left, every line is 1,000 ft

– You do not have to label every line…it is probably easiest to label every other line.

• On bottom, every line is 100 km. – It is probably easiest to label every other line, or even

every fifth line.

• Label both axis (“Distance (km)” & “Depth (ft)”)• Neatly write the following title at the top. “Profile

of Ocean Floor from New Jersey to Portugal”

Double Check

• Graph titled & axes labeled (with units)

• All landforms labeled (listed in # 10)

• All questions answered (including # 1)

• Work shown & units included in all numerical answers

Ocean Measurements

• Nautical mile– 1 minute of arc of latitude along any meridian– 1 Nautical mile = 1.15 mi = 1.85 km

• Knot– 1 Nautical mile/hr– 1 knot = 1.15 mi/hr

Ocean Measurements

• Fathoms– Measurement for water depth

1. To penetrate to the meaning or nature of; comprehend.

2. To determine the depth of; sound.

– Originally based on arm span– 1 fathom = 2 yards = ___ feet

Light Zones of the Ocean

• 3 Light zones– Sunlit Zone 0 – 600 ft _____ fathoms– Twilight Zone 600-3000 ft _____ fathoms– Midnight Zone 3000+ ft _____ fathoms

Page 13: Schedule 10 min notes, then work on graph Explain each step each day Day 1 start, get chart done can work with neighbor! Can’t change seats Day 2 CHECK.

Sunlit Zone

• 0 – 600 ft _____ fathoms– Enough light for photosynthesis to occur– 90% of all marine life live here!– Phytoplankton lives here, forming base of

food chain

Page 14: Schedule 10 min notes, then work on graph Explain each step each day Day 1 start, get chart done can work with neighbor! Can’t change seats Day 2 CHECK.

Twilight Zone

• Some light, not enough for photosynthesis

• Large eyes or bioluminescense requred for seeing

• Squid, jellyfish, lantern, and hatchet fish live here

• Invitation to a mealBioluminescence can serve as a lure to attract prey. The viperfish, Chauliodus sloani, has a luminescent lure on the end of a modified fin ray that it can arch forward in front of its mouth. In the dim depths, all that the viperfish's would-be prey sees is a glowing morsel. When this prey comes in close, the viperfish quickly impales it with its enormous, viper-like fangs. These fangs are so long that if

they were fully inside its mouth, the fish would impale its own brain.

Deep Sea Shrimp• Confused yet, viperfish?

Atolla Jellyfish

• Someone big help me!!!!

Loosejaw Fish

Hatchetfish • Bioluminescence can provide effective camouflage. In the twilit

depths, the silhouette of an animal against the sunlight filtering down is an easy target. This is why many open-ocean predators like the hatchetfish have upturned eyes and mouths. But the hatchetfish itself is prey to bigger fish swimming below it. It's narrow silhouette and silver sides make it harder to see, but it also emits light from its belly that is a perfect match in color and intensity to sunlight filtering down. If a cloud dims the sunlight, the fish dims its bioluminescence—a trick called counterillumination.

Squid & Lanternfish

• Counterillumination is popular!

Anglerfish

• Bacteria provide the bioluminescence!

Blackdragon Fish

• Signal mate, lure fish, burglar alarm, camouflage

Midnight Zone

3000+ ft

• No light, water temp near freezing!

• Most life in this zone lives in hydrothermal vent communities– Bacteria feeds on methane and hydrogent

sulfide, forming base of food chain– Larger animals feed on bacteria…

• Angler fish, tripod fish, sea cucumbers live here
